Assessment of Diffusion and Perfusion01:17

Assessment of Diffusion and Perfusion

1.3K
Understanding and evaluating diffusion and perfusion is critical in assessing a patient's respiratory and circulatory health. These processes play key roles in maintaining the body's internal environment, ensuring that tissues receive adequate oxygen while waste products are efficiently removed.
The Role of Diffusion in Respiration
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the respiratory system, this...

Synthesis and Regulation of Thyroid Hormones

6.6K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Area of Science:

  • Neuroimaging
  • Radiology
  • Endocrinology

Background:

  • Hashimoto's thyroiditis (HT) is an autoimmune thyroid disease.
  • Diffusion tensor imaging (DTI) assesses brain microstructural integrity.
  • Brain involvement in HT is not fully understood.

Purpose of the Study:

  • Investigate DTI differences in patients with HT.
  • Examine the relationship between DTI metrics and disease duration.
  • Explore correlations between DTI values and thyroid peroxidase antibody (TPOAb) levels.

Main Methods:

  • Prospective study including 36 HT patients and 18 healthy controls.
  • DTI parameters (FA, MD, AD, RD) measured in 15 neuroanatomical locations.
  • Comparison of DTI values between HT patients and controls.

Main Results:

  • HT patients showed lower FA in cingulum, globus pallidus, and cerebellar white matter.
  • Elevated MD in cerebellar white matter and higher RD in cingulum/cerebellar white matter observed in HT.
  • Negative correlation between FA and TPOAb in posterior limb of internal capsule; positive correlation between MD and TPOAb in corona radiata.

Conclusions:

  • DTI reveals significant microstructural brain alterations in patients with Hashimoto's thyroiditis.
  • These changes occur in neurocognitive-related brain regions.
  • Findings suggest a potential link between HT and neurological dysfunction.
